We stopped in to Waimea Coffee Company many times during our stay in Waimea. The staff is friendly, the coffee tastes good, and there are plenty of gluten free food options, including baked goods (there is usually at least 1 per day).
The staff definitely puts their passion into making each coffee drink - they even put those cute little designs on top and will go the extra mile for the kiddos.
The only reason this cafe gets 4 stars instead of 5 is the wait. They are currently hiring (and therefore understaffed), and are typically so busy that you should expect to wait about 10 minutes to get your drink order. We typically ordered one Americano and one Mocha or something similar; however, one day I ordered Earl Grey and it still took 10 minutes. But their coffee is good, so it's worth it if you can wait.
If you're not in a rush, Waimea Coffee Company is a great place to get your morning cup of joe.
